chore(deps): bump langgraph-checkpoint to 4.2.0 / postgres 3.1.2 and delete the saver patch (#5734)
* chore(checkpoint): bump to checkpoint 4.2.0 and drop the stale saver patch

langgraph-checkpoint 4.2.0 fixes the write dropped after a full -> delta
migration (upstream langchain-ai/langgraph#8526) and keeps its own
InMemorySaver override, so the compatibility patch in checkpoint_patches.py
could neither detect the fix nor stand down: it read langgraph's version
while InMemorySaver ships in langgraph-checkpoint, and it would have kept
shadowing the upstream implementation on 4.2.0. The postgres release 3.1.2
locates plain-value delta seeds (upstream #8535).

- floor langgraph-checkpoint>=4.2.0,<5.0 in the harness and raise the postgres
  extra to >=3.1.2,<3.2; langgraph's own >=4.1.0 would otherwise let a
  resolver reintroduce the bug now that the patch is gone
- delete the patch, its version guard, and the three implementation-assertion
  tests; test_full_to_delta_migration_replays_on_same_thread stays as the gate
  and fails on 4.1.1 without the patch (verified by a one-off unpatch run)
- langgraph stays 1.2.9 and langgraph-checkpoint-sqlite stays 3.1.1

Verification: make lint; delta checkpointer/cache/worker-resume suites green
with the migration gate passing on memory and sqlite (postgres params skip
without TEST_POSTGRES_URI). The full make test run before the packaging-pin
fix below was 13 failed / 18523 passed; 12 of those failures reproduce on main
with the same environment (git stash baseline, identical failure sets), 7 of
them because the local config.yaml runs checkpoint_channel_mode: delta. The
remaining one, the postgres-extra string pin in tests/test_checkpointer.py, is
updated here.

Upstream status for the surrounding gaps: cache parity across off/cold/warm
states, postgres pagination (langchain-ai/langgraph#8448) and parallel-superstep
replay order (#8382) are still open upstream, as is the abandoned-branch fork
fix (#8548) that the delta resume linearization in runtime/runs/worker.py works
around, so that path stays.

fix(scripts): detect the ollama extra from configured models (#5318)
* fix(scripts): detect the ollama extra from configured models

make dev synced without --extra ollama, uninstalling langchain-ollama from a working setup. Same failure #2754 hit with postgres; ollama predates the detector added in #2767 and never got a rule.

* fix(deps): declare the ollama extra on backend, pin model use: matching

Review follow-ups.

`ollama` was the only extra in the detector's map that the root `backend`
project did not declare, so any consumer syncing without
`--all-packages` failed outright:

    $ cd backend && uv sync --locked --extra ollama
    error: Extra `ollama` is not defined in the project's
    `optional-dependencies` table

`serve.sh` and `docker/dev-entrypoint.sh` both pass `--all-packages` and
were unaffected, but `backend/Dockerfile` does not, and
`config.example.yaml` documents `UV_EXTRAS` as an image build-arg — so
`UV_EXTRAS=ollama docker compose build` would have hard-failed on a
value this branch makes first-class. Declaring
`ollama = ["deerflow-harness[ollama]"]` alongside the other delegating
extras closes that, and `uv.lock` is regenerated to match.

The `use:` match also accepted any nesting depth inside `models:`, so a
`use` in a sub-mapping was read as the model's provider:

    models:
      - name: doubao
        use: deerflow.models.patched_deepseek:PatchedChatDeepSeek
        when_thinking_enabled:
          use: langchain_ollama:ChatOllama

That yielded `--extra ollama` despite the model's own provider pointing
elsewhere, and `when_thinking_enabled` appears fifteen times in
config.example.yaml, so the shape is common rather than contrived. Pin
matching to the list item's own key indent, mirroring how
`section_value()` pins `child_indent` and documents deeper nesting as
ignored on purpose. Covered by a regression test that fails on the
looser parser.

* chore(deps): drop unrelated standard-aifc marker churn from uv.lock

Review follow-up. Regenerating the lock with a newer local uv (0.11.19)
also rewrote the `standard-aifc` entry, adding
`python_full_version >= '3.13'` markers to its `audioop-lts` and
`standard-chunk` dependencies. Unrelated to this change, so restore
upstream's lines and keep the lock diff to the `ollama` extra.

`uv lock --check` passes with these lines under both the CI- and
Dockerfile-pinned uv 0.11.1 and uv 0.11.19.

* fix(scripts): detect ollama in unindented model lists and after nested sequences

Review follow-ups on the models parser.

`yaml.safe_dump` — used by the setup wizard (`make setup`) and
scripts/config-upgrade.sh — writes list items unindented:

    models:
    - name: qwen3-local
      use: langchain_ollama:ChatOllama

The parser treated any column-0 line as the end of the `models:` section,
so the first model ended it and nothing was detected. That is the layout
new users get from the recommended setup path, so `make dev` still synced
without `--extra ollama`. Model entries are now recognised before the
section-end test, the same ordering `tools_include_name()` already uses
for the unindented tools list (#4367).

Separately, every sequence item reset the key indent, including items
inside a model option. With `stop:` / `- END` before `use:`, the key indent
jumped to the nested item's and the model's own `use` was skipped, so
detection depended on key order within the model.

The first sequence item under `models:` now fixes the model-list indent;
only items at that indent start a model and set where its keys sit.
Nested sequence items and deeper mappings are skipped without moving it.

Regression tests cover the real setup-wizard output via
`build_minimal_config()`, a hand-written unindented list, and `use:`
after a nested `stop:` list — all three fail on the previous parser — plus
a guard that a `- use:` nested inside a model option is still ignored.

fix(agents): make the injected current-date timezone configurable (#5154)
* fix(agents): make the injected current-date timezone configurable

## Why

The date reminder injected into the lead and subagent prompts (DynamicContextMiddleware / SubagentDateContextMiddleware) was formatted with the server's local wall clock. DeerFlow containers default to UTC, so a user in Asia/Shanghai chatting in the 00:00-08:00 window was told that 'today' is the previous day - the model then reasons, plans, and date-stamps against the wrong day.

## What changed

- _format_current_date() now reads the optional DEER_FLOW_DATE_TIMEZONE env var (IANA name, e.g. Asia/Shanghai) and renders the date in that zone.

- Unset = unchanged server-local behavior; invalid names log a warning and fall back to server-local.

- Documented the knob in config.example.yaml, the module docstring, and the DynamicContext entry in agents/middlewares/AGENTS.md.

## Surface area

- [x] Agents / LangGraph - prompt-layer date context only; message shape and midnight-update behavior unchanged

- [ ] Frontend UI / Backend API / Sandbox / Skills / Dependencies

- [x] Default behavior change (opt-in via env var - no behavior change unless set)

## Bug fix verification

- New tests: test_format_current_date_honors_configured_timezone (UTC 20:30 -> 2026-09-03 in Asia/Shanghai), test_format_current_date_defaults_to_server_local_without_env, test_format_current_date_invalid_timezone_falls_back.

- Existing mocked-datetime tests pass unchanged (no env -> datetime.now() path).

## Validation

- cd backend && python -m pytest tests/test_dynamic_context_middleware.py: 31 passed.

- blocking_io/test_dynamic_context_middleware.py: 2 pre-existing abefore_agent failures reproduce identically on clean main (blockbuster os.listdir detection on this host); the other 2 pass.

- ruff format + ruff check clean.

* fix(agents): avoid passing tz to datetime.now when no timezone is configured

CI (backend-unit-tests shard 2) failed in test_tool_error_handling_middleware.py::test_subagent_chain_injects_date_without_memory_and_coalesces_for_strict_provider because its _FrozenDateTime.now() subclass override accepts no arguments, while _format_current_date() called datetime.now(None) even when DEER_FLOW_DATE_TIMEZONE was unset.

- _format_current_date() now calls datetime.now() with no arguments unless a timezone is actually configured, preserving the exact legacy call shape for every datetime-subclass test fake.

- The configured-zone path still calls datetime.now(tz) and converts via astimezone(tz).

- Updated the no-env unit test to assert datetime.now() is called without arguments.

Validation: python -m pytest tests/test_dynamic_context_middleware.py + the previously failing strict-provider test: 32 passed. ruff clean.

* fix(agents): declare the effective current-date timezone in the assembly descriptor

## Why

Maintainer review on the DEER_FLOW_DATE_TIMEZONE change (#5154): the knob is
prompt-affecting, yet both DynamicContextMiddleware and SubagentDateContextMiddleware
were invisible to the agent assembly descriptor - describe_middleware() fell back to
{"probed": true} for unset, UTC, and Asia/Shanghai alike, so deployments that inject
different dates shared one assembly fingerprint and release observers could not
distinguish or audit the behavior change.

## What changed

- Both middlewares now implement release_policy_parameters() -> dict[str, object],
  declaring {"current_date_timezone": <name>} as required by the module's middleware
  self-description contract.

- The declared value is the normalized effective zone: a configured, valid
  DEER_FLOW_DATE_TIMEZONE is reported by its IANA key (ZoneInfo.key); otherwise the
  server-local zone is resolved to its IANA key when the platform exposes one and to
  its tzname label otherwise (fixed-offset hosts), with "UTC" as the final fallback.

- Added both middlewares to _MIDDLEWARE_DECLARATIONS in
  backend/tests/test_middleware_release_policy.py so the existence check and the
  construct-and-canonical-hash check cover them.

## Verification

- New tests: test_date_middlewares_declare_configured_timezone (Asia/Shanghai),
  test_date_middlewares_declare_utc_timezone, plus resolved-server-local assertions
  for the unset and invalid-env paths; both middlewares agree in every case.

- cd backend && python -m pytest tests/test_dynamic_context_middleware.py
  tests/test_middleware_release_policy.py: 70 passed.

- Regression spot-check: tests/test_agent_assembly_descriptor.py,
  tests/test_tool_error_handling_middleware.py, tests/test_system_message_coalescing_middleware.py:
  102 passed.

- ruff check + ruff format clean.

* fix(agents): stabilize the declared date timezone and simplify the formatting path

## Why

Follow-up review on #5154 (willem-bd). The release-policy declaration added in
884cec4b resolved the observability gap but pinned far less identity than its
docstrings claimed, and the formatting path carried a production no-op.

## What changed

- The declared label is now stable and unambiguous: a configured, valid
  DEER_FLOW_DATE_TIMEZONE is reported by its IANA key; without one, the
  server-local zone is resolved to a real IANA key from the TZ env var or the
  /etc/localtime symlink (Linux/macOS); when no key is recoverable (Windows,
  stripped containers) the declaration falls back to a stable
  `server-local(+-HH:MM)` sentinel carrying the current UTC offset. It never
  reports a bare abbreviation - datetime.now().astimezone() yields only a
  fixed-offset timezone whose tzname (e.g. CST, EST/EDT, CET/CEST) is
  ambiguous or DST-churns, which the assembly descriptor docstring says must
  not happen.

- Dropped the redundant astimezone(tz) in _format_current_date():
  datetime.now(tz) already returns the instant expressed in tz. The
  configured-zone test now fakes datetime.now(tz) semantics (the fixed instant
  converted into the requested zone) instead of relying on that conversion.

- Documented why the knob is an env var, not a config-schema field: it is read
  at runtime by both date-context middlewares so an operator can point a
  container at another zone without mounting a config.yaml (module docstring +
  config.example.yaml note).

- AGENTS.md: fixed the glued DynamicContext sentence (missing separator).

- Added tzdata>=2025.1 to the harness runtime dependencies (with uv.lock) so
  ZoneInfo works on stripped containers / Windows without an OS zone database.

## Verification

- New tests: test_server_local_timezone_name_reads_tz_env,
  test_effective_timezone_sentinel_uses_offset_when_local_zone_is_not_resolvable;
  reworked test_format_current_date_honors_configured_timezone to exercise the
  real datetime.now(tz) path.

- cd backend && python -m pytest tests/test_dynamic_context_middleware.py
  tests/test_middleware_release_policy.py tests/test_agent_assembly_descriptor.py
  tests/test_tool_error_handling_middleware.py: 140 passed.

- ruff check + ruff format clean.

* fix(agents): offload subagent date injection off the event loop

## Why

Follow-up review on #5154 (willem-bd, P2): SubagentDateContextMiddleware.abefore_agent()
called _inject() directly, so enabling DEER_FLOW_DATE_TIMEZONE could synchronously
read the OS timezone database (or the tzdata wheel) on a cold cache - filesystem
work on the async subagent execution path whenever no assembly observer resolved the
zone first.

## What changed

- SubagentDateContextMiddleware.abefore_agent() now offloads the injection via
  asyncio.to_thread with the same bounded timeout DynamicContextMiddleware uses
  (issue #3402); on timeout it logs and skips the date update for that run instead
  of blocking the loop.

- Narrowed the exception handling in _date_timezone() and the TZ-env branch of
  _server_local_timezone_name() to configuration-shaped failures
  (ZoneInfoNotFoundError / ValueError / OSError). Previously a blanket
  `except Exception` also swallowed BlockingError raised by the blocking-I/O
  regression gate, mislabeling a loop-blocking call as an invalid timezone and
  silently degrading to server-local - which made the new regression anchor
  useless. Other exceptions now propagate.

## Verification

- New blocking-I/O regression anchor
  (backend/tests/blocking_io/test_subagent_date_context_middleware.py): drives a
  real create_agent graph under the strict Blockbuster gate with the knob enabled
  and asserts the date reminder is injected. Verified it fails (BlockingError) when
  the offload is reverted and passes with it in place.

- python -m pytest tests/blocking_io/test_subagent_date_context_middleware.py:
  1 passed. The two pre-existing os.listdir failures in
  tests/blocking_io/test_dynamic_context_middleware.py reproduce unchanged on this
  host (same as clean main).

- python -m pytest tests/test_dynamic_context_middleware.py
  tests/test_middleware_release_policy.py tests/test_tool_error_handling_middleware.py
  tests/test_agent_assembly_descriptor.py: 139 passed; the single
  ToolReceiptMiddleware-ordering failure reproduces with the change stashed
  (local extensions registry, unrelated to this PR).

- ruff check + ruff format clean.

* fix(agents): read the direct /etc/localtime symlink target for the zone key

## Why

Follow-up review on #5154 (willem-bd, P2): on macOS, /etc/localtime commonly
points to /var/db/timezone/zoneinfo/<zone>, but Path.resolve() follows that
directory's own symlink and yields a versioned path such as
/private/var/db/timezone/tz/2026c.1.0/zoneinfo/Asia/Shanghai, which matched no
configured prefix. The server-local resolution then returned None and the
assembly descriptor fell back to a server-local(+HH:MM) sentinel even though
the IANA key was available - conflating zones that share an offset and making
DST-based fingerprints unstable.

## What changed

- _server_local_timezone_name() now reads the direct symlink target via
  os.readlink("/etc/localtime") instead of Path.resolve(), so macOS' unversioned
  zoneinfo path is seen as-is and its IANA key is preserved.
- The zone key is taken from whatever follows the last "/zoneinfo/" segment,
  which also handles Apple's canonical versioned path when a direct target
  already carries it, and relative targets are normalized against /etc.
- Removed the now-unused Path import and the fixed zoneinfo prefix tuple.

## Verification

- New tests: test_server_local_timezone_name_reads_direct_macos_symlink_target,
  test_server_local_timezone_name_reads_apple_versioned_symlink_target, and
  test_server_local_timezone_name_normalizes_relative_symlink_target.

- python -m pytest tests/test_dynamic_context_middleware.py
  tests/test_middleware_release_policy.py tests/test_agent_assembly_descriptor.py:
  105 passed (75 after re-running the first two on the merged main). The blocking
  subagent anchor still passes; the two pre-existing os.listdir blocking failures
  on this host are unchanged.

- ruff check + ruff format clean.

feat(ci): split backend unit tests into parallel shards (#5137)
* feat(ci): split backend unit tests into parallel CI shards

Split the single offline backend `make test` job into four GitHub Actions
matrix shards (SPLITS=4, GROUP=1..4) via pytest-split, so the ~12k-test suite
runs in parallel instead of in one 15-minute job. Each shard runs on its own
runner with its own Postgres/Redis services; fail-fast: false lets a failing
shard report its owned tests without cancelling its peers.

`make test` stays the canonical full-suite entry point; CI now calls the new
`make test-shard SPLITS=4 GROUP=N`. tests/blocking_io remains owned solely by
the dedicated blocking-I/O workflow (excluded via --ignore), extending #5105.

Fixes #5088

* test(ci): make backend test shards duration-aware and pin the contract

Make `make test-shard` an explicit least_duration split that READS
backend/.test_durations (read-only for shards, so concurrent CI jobs never
race writes on it), and add `make test-shard-durations` to regenerate that
file from the full offline suite. Update the CI unit-test workflow contract to
call `make test-shard SPLITS=4 GROUP=<n>` and assert the shard command carries
--splits 4, --group 2, -m "not live", --ignore=tests/blocking_io and
--splitting-algorithm least_duration. Verified on the real 13,140-test normal
suite that the four shards are pairwise disjoint and their union equals the
unsplit suite.

Refs #5088

* test(ci): fail fast when the duration baseline is missing

`make test-shard` now requires backend/.test_durations and exits with a clear
error instead of letting pytest-split silently degrade to an even (count-based)
split. Harden the CI contract test to pin `--durations-path=.test_durations` and
to assert the repo ships the committed duration baseline.

Refs #5088

* docs: trim backend/AGENTS.md within guidance budget

* test(ci): add backend test duration baseline

Add the duration baseline generated by a full offline backend run on a
GitHub-hosted ubuntu-latest runner (the same runner type the shards use), so
`make test-shard` balances the four matrix shards by real wall-clock cost.

Refs #5088

* test(ci): make the duration writer honor DURATIONS_FILE

`test-shard-durations` now writes `--durations-path=$(DURATIONS_FILE)` instead of a
hard-coded .test_durations, so the reader and writer stay consistent when the
path is overridden.

fix(deps): depend on renamed tenki package instead of tenki-sandbox (#5087)
* fix(deps): depend on renamed tenki package instead of tenki-sandbox

tenki-sandbox has been removed from PyPI and republished as tenki. Its old wheel URL still resolves, so existing lockfiles keep installing and the breakage is invisible to anyone with a warm lock; any fresh resolution fails with 'tenki-sandbox was not found in the package registry'.

tenki 1.0.2 still ships the tenki_sandbox module, so the imports in community/tenki/provider.py and sandbox.py are unchanged.

Fixes #5081

* fix(tenki): point install guidance at the renamed distribution

The rename to `tenki` left the user-facing remediation still naming the
removed package. `_import_client` raised "pip install tenki-sandbox" on the
missing-extra path — the exact instruction this change proves now 404s on
PyPI, handed to the user at the exact moment they need it to work.

Update that message and the remaining `tenki-sandbox` references in the
provider, sandbox adapter, README, sandbox AGENTS.md and the test docstring.
The imported module stays `tenki_sandbox`, so the distribution and module
names now differ; each mention says so rather than just swapping the string.

No behavior change beyond the error text.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(tenki): migrate the provider to the 1.x workspace-only API

Renaming the dependency was not enough. tenki 1.0.2 keeps the tenki_sandbox
module name but not its contract: Client.create dropped project_id and has no
**kwargs to absorb it, and IdentityWorkspace no longer carries `projects`
(the attribute is gone from the package entirely). Both configuration paths
therefore failed before a sandbox could be created — explicit project scope
raised TypeError, and automatic scope raised AttributeError walking
workspace.projects.

Scope is now the workspace alone. _resolve_scope returns a single workspace id,
auto-selecting when the account has exactly one, and project_id is gone from
create_kwargs and from the documented config surface.

A stale project_id in config.yaml warns rather than fails. SandboxConfig is
extra="allow", so simply not reading the key would leave it scoping nothing
with no signal; it also used to short-circuit the identity lookup, so operators
with more than one workspace need to know they must now set workspace_id.

The suite passed against the broken provider because the fake client took
**kwargs and swallowed the project_id the real SDK rejects. The double now
mirrors 1.0.2 — keyword-only, no **kwargs — so an unexpected argument is a
TypeError in tests exactly as it is against the SDK. Reintroducing the old
create call fails 20 tests; before this change it failed none.

Verified against the exact locked wheels: every other kwarg the provider
passes (name, workspace_id, sticky, wait, max_duration, image, cpu_cores,
memory_mb, env) and every SDK surface it touches (who_am_i, Identity.workspaces,
wait_ready, exec, close, the fs API, the four terminal exception classes) is
unchanged in 1.0.2.

Reported by willem-bd in review.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(config): drop sandbox.project_id from the Tenki example

The canonical example still documented project_id as a supported optional key
after the provider stopped honouring it, so an operator following it could set
the key, get no scope from it, and hit a workspace-resolution failure with
nothing in the example to explain why.

Replaced with a migration note rather than a silent deletion: someone upgrading
already has the key in their config.yaml and needs to know it is inert now and
that workspace_id is what scopes a sandbox on Tenki 1.x.

feat(extensions): let an out-of-tree extension observe what the agent did (#4863)
* feat(extensions): let an out-of-tree extension observe what the agent did

DeerFlow's extension system can contribute middleware, services and routes,
but an extension cannot answer basic questions about a run without reaching
into host internals. Several of the facts it would need are destroyed by the
operations that produce them:

  * The middleware chain injects and rewrites a lot of context — date
    reminders, recalled memory, compaction summaries, durable-context data,
    image payloads, activated skill bodies. Downstream, none of it is
    attributable: at the model-call boundary an injected HumanMessage is
    indistinguishable from the user's own, and anything wanting to tell them
    apart has to pattern-match prompt wording, which breaks on the next copy
    edit.

  * Two runs of "the same agent" are only comparable if the chain enforced the
    same limits, prompts and thresholds. Recovering that from outside means
    reading private attributes and guessing which of them change behaviour — a
    guess that rots silently as middlewares gain fields.

  * The lead-agent factory resolves a model after runtime overrides, renders a
    prompt, filters tools through authorization and composes a stack, all
    inside one synchronous call, and none of it survives: a middleware sees its
    neighbours but not the prompt, the run worker sees a graph but not what
    went into it.

  * Summarization is destructive by design. N messages leave the context and
    one summary enters it; afterwards only the summary exists, so "which
    messages became this?" is not reconstructible.

This adds seven neutral facilities so those facts are recorded where they are
still true, and releases the contract package as 0.2.0.

Message provenance
  Producers stamp `deerflow_content_kind` / `deerflow_producer_kind` onto the
  messages they inject or rewrite. Stamping is unconditional — a fact whose
  presence depends on whether an observer is installed is not a fact — and the
  keys are server-owned, so provenance cannot be forged from a request.

Middleware self-description
  Twelve middlewares declare their own behaviour-affecting parameters through
  a duck-typed `release_policy_parameters()`. Long text is hashed rather than
  embedded: a declaration is an identity, not a copy of the prompt.

Agent assembly descriptor
  `assemble_lead_agent()` returns the graph plus a descriptor whose fingerprint
  answers "did anything about this agent change between these two runs?".
  `make_lead_agent()` keeps its graph-only signature — it is the LangGraph
  Server ABI declared in langgraph.json. Tools and skills are sorted before
  hashing because their assembly order is incidental; middlewares are not,
  because stack order decides what wraps what. Host build identity is reported
  but excluded from the fingerprint, so a redeploy does not invalidate every
  agent's identity.

Context compaction observation
  Summarization emits the content hashes of the messages it is about to remove
  joined to the summary that replaced them. Content is the only identity
  available at that seam: the summary does not become a message, and what later
  projects it into a request renders it bounded and escaped rather than
  verbatim.

Neutral policy, transform and MCP-source facts
  Guardrail decisions are published to runtime context under a `__`-prefixed
  key; result-rewriting middlewares append a declared, ordered transform trail;
  MCP tools carry their credential-free logical origin.

Extension route identity
  Contributed routes are session-authenticated and cannot opt out, but
  "logged in" and "administrator" are different questions. Extensions get a
  neutral projection of the caller rather than the host's auth context, and
  `require_admin` fails closed when identity cannot be determined.

Extension-owned tables
  An extension that persists data owns its own MetaData and migration chain, so
  its tables are absent from Base.metadata and `alembic revision --autogenerate`
  proposes dropping them. Extensions declare a table prefix, which is rejected
  at registration if it would shadow a host table.

The contract package stays dependency-free and imports no host code; every new
Protocol method has a default so later additions remain additive. The loader's
pre-1.0 rule requires an exact major.minor match, so extensions written against
0.1 are now refused at startup with an actionable install hint rather than
loading into a host that implements a different surface.

uv.lock records the contract package's new version, so `uv sync --locked` still
resolves on a fresh checkout.

feat(extensions): add gateway contribution points and packaged extension management (#4780)
* feat(extensions): add gateway services and routers

* feat(extensions): add standalone reference extension

* fix(extensions): harden contributed gateway routes

* docs(extensions): document gateway contribution points

* feat(extensions): add operator CLI for packaged extension management

Add `deerflow extensions install/list/enable/disable/remove` plus the root
`make extension-*` wrappers, backed by an `ExtensionManager` that owns one
transaction over backend/pyproject.toml, backend/uv.lock, the managed source
snapshot, the uv environment, and the `plugins:` block in config.yaml.

Install accepts a package requirement, a public HTTPS Git URL, or a local
directory. Local directories are copied to backend/extensions/sources/ as
deployable snapshots rather than editable installs, and the root .dockerignore
re-includes that tree so snapshots reach the backend builder. Remote sources are
HTTPS-only; SSH Git, file:// and local wheels are rejected because the stock
Docker builder cannot reproduce them.

Because environment configuration can still resolve a plain package name to a
local wheel (a UV_FIND_LINKS wheelhouse, say), every uv add/remove is followed
by an audit of the new lock: any local reference the stock image build cannot
reproduce rolls back the whole transaction. A config carrying duplicate
top-level `plugins:` keys is rejected outright rather than managed against one
block while the Gateway reads another.

Dependency synchronization now has one lock authority. The `extensions`
dependency group joins [tool.uv].default-groups, every startup path syncs the
same lock with --locked and launches with --no-sync, and the Docker images move
to uv 0.11.1 for the --no-workspace boundary the manager needs.

Loader gains `enabled`, `name` and `package` fields so a disabled extension is
skipped before resolution and import.

* fix(extensions): stop the managed plugins rewrite from destroying config

Two data-safety defects in the managed `plugins:` block writer.

The "next top-level key" boundary was a regex matching only
`[A-Za-z_][A-Za-z0-9_-]*` or a quoted key. `AppConfig` is `extra="allow"`, so a
config may legally carry any top-level key, and a key the pattern cannot
recognize did not fail loudly — it read as "no next section", and the rewrite
replaced that neighbour and its entire subtree with the managed block. `my.key`,
`2fa`, `$schema`, `my key` and non-ASCII keys were all silently deleted by a
plain `extension-enable`/`disable`. Both boundaries now come from the YAML
parser's node marks, so key shape is irrelevant.

The file-final branch never consulted the trailing-comment scan the has-next-key
branch used, so any comment below the block was dropped. Since the manager
appends `plugins:` at end of file, that is the steady-state shape for most
installs: an operator note below the block was destroyed on the next toggle.

Separately, every managed install wrote `required: true` while the loader
defaults to false. That turned any later load failure — broken wheel, missing
native library, deleted snapshot — into a Gateway startup abort recoverable only
with shell access. New records are now written `required: false`, with an
explicit `install --required` opt-in; adopting an existing hand-written record
still preserves the operator's own choice.

* fix(extensions): harden the manager transaction and correct its docs

Follow-up hardening on the extension package manager.

Security posture, which the docs already claimed:
- Scrub `UV_PYTHON`, `UV_INSECURE_HOST`, `UV_CONSTRAINT` and
  `UV_NO_BUILD_ISOLATION` from the controlled uv environment. `UV_PYTHON` swaps
  the interpreter that the entry-point probe then imports and calls, and every
  later `uv run --no-sync` startup uses; `UV_INSECURE_HOST` removes the TLS
  validation the HTTPS-only source rule depends on. Neither is an index, proxy,
  cache or credential-provider setting, so neither was covered by the carve-out.
- Recognize run-together and all-caps secret query parameters (`accesstoken`,
  `ACCESSTOKEN`, `key`, `pw`, `sas`, `code`). The camel-case splitter only fires
  on case transitions, so only the separated spellings were caught. Short
  generic words stay boundary-anchored, so `?keyword=` remains installable.
- Validate the config before running any uv command. `uv add`/`uv sync` execute
  the package's build backend, so a config the manager could never write to must
  fail before that code runs rather than afterwards through rollback.

Transaction integrity:
- Run the second dependency-file restore from a `finally`. The recovery sync
  runs without `--locked` when the checkout had no lock, so uv writes one while
  resolving; if that sync then failed, the restore was skipped and the operator
  kept a lock file they never had. A failing recovery sync now also reports the
  original failure instead of replacing it.
- Skip the recovery sync on cancellation. Answering Ctrl-C with a full
  dependency resolve invites a second interrupt that escapes the handler and
  strands the checkout mid-transaction; the declarations are already restored
  and the next locked startup sync reconciles the environment.
- Retry a non-blocking lock on Windows instead of using `msvcrt.LK_LOCK`, which
  gives up after ~10s — far shorter than a real `uv add` plus `uv sync`, so
  contention surfaced as `Permission denied` rather than serializing.
- Locate the entry-point probe's JSON payload instead of parsing stdout's first
  line, so a `sitecustomize`/`.pth` banner cannot roll back a good install.
- Warn when the lock records a loopback source. `127.0.0.1` inside the image
  builder is a different machine, but unlike an environment-driven wheelhouse
  resolution this is a source the operator typed deliberately, so it is reported
  rather than rolled back. Private-network indexes are untouched: a builder on
  that network can reach them.

Docs: the blanket claim that failed operations restore the config file was
wrong — the conflict branches deliberately preserve a concurrent external edit
and leave `remove` deactivated. Document that, the `required: false` default,
the config preflight, the interrupt behaviour, and where the plugins-block
boundaries come from.

* test(gateway): pin the request-path projection agreement

`get_request_route_path()` imports the private
`starlette._utils.get_route_path` so the auth and CSRF predicates classify
the exact string Starlette's router matches on. Its requirement is not
"strip root_path correctly" but "return what the dispatcher is matching",
so delegating to the router's own implementation keeps the two in lockstep
by construction. Keep the private import rather than vendoring a copy: an
import that disappears fails loudly at startup, while a stale copy diverges
silently at a security boundary.

Cover the property directly instead of the mechanism, so the tests survive
a future reimplementation:

- projection edge cases, including the segment-boundary guard that keeps
  root_path="/api" from slicing "/apifoo/models" into a string the router
  would never match
- agreement with the router under nested mounts
- the two bypasses these predicates exist to prevent: a protected route
  mounted under the "/health" public prefix must still 401, and a POST
  mounted under "/api/webhooks" must still require a CSRF token

Both are verified to fail when the projection is reverted to
`request.url.path` (9/13 red) and when a plausible vendored copy omits the
boundary guard (the 2 boundary cases red).

Declare starlette as a bounded direct dependency so a bump — which is
security-relevant here — shows up in review rather than arriving silently
through FastAPI.

* ci: pin uv to the version production ships

ExtensionManager is not a consumer of uv the build tool -- it is a program
whose whole job is driving `uv` as a subprocess, depending on its CLI
behavior (`--no-workspace`, `--no-sync`, what `uv add` writes into
`[dependency-groups] extensions`) and on the `uv.lock` serialization format.
uv is closer to a runtime dependency with a contract than to incidental
tooling.

backend/Dockerfile pins that binary to 0.11.1, but all eight
astral-sh/setup-uv steps installed whatever was latest at run time, so CI
exercised the manager against a uv that is not the uv production runs. The
sharpest failure that allows: a newer uv bumps uv.lock's `revision`, CI
stays green because the same uv reads back what it wrote, and the pinned uv
in the production image cannot read the committed lock. `uv lock --check`
is version-sensitive for the same reason -- it verifies the lock is what
*this* uv would produce, and two versions can emit equivalent but
non-identical output.

Pin every step to 0.11.1 and lift the one lingering setup-uv@v3 to v7 so
the steps share input and caching behavior.

Pinning alone drifts apart again on the next bump, so add a constraint test
in the style of test_compose_default_bind_host.py: the Dockerfile's
UV_IMAGE tag is the single source of truth, and both compose defaults plus
every setup-uv step must match it. Verified to fail when a pin drifts, when
a step omits `version`, and -- the real scenario -- when the Dockerfile is
bumped alone, which lights up the workflows and both compose files at once.

* fix(gateway): state the extension route auth limit and abort a failed dev sync

Two scoped review follow-ups.

README: contributed routers cannot enter the host's reserved public prefixes,
which makes every extension endpoint session-authenticated -- there is no way
to expose an unauthenticated route. The rejection rule was documented but its
consequence was not, so inbound provider webhooks and public status endpoints
read as merely undocumented rather than out of scope for this release.

docker/dev-entrypoint.sh: the self-heal retry reuses `--locked`, so it repairs
a corrupt .venv but never a lock that disagrees with pyproject.toml. `set -e`
already stopped the script there -- uvicorn was not being started against a
stale environment -- but it exited on a bare uv exit code with no indication of
what to do. Abort explicitly with the cause and the fix.

Tests slice the sync block out of the real script and run it against a stub uv,
so they exercise the shipped code rather than a copy of it (/app/backend only
exists inside the container). They cover the success path, the retry that
recovers, the abort, and the guidance. Verified against the pre-fix script:
only the guidance case goes red, confirming the abort itself was already
correct.

* fix(extensions): point Git SSH shorthand at the HTTPS correction

Git's SCP-like shorthand carries no URL scheme, so `git+git@host:org/repo.git`
reached the scheme rules looking like a bare path and was rejected with
"local path references are not deployable; pass a local directory so DeerFlow
can snapshot it". The operator asked for a remote source, so that guidance
points at the wrong fix. Detect the shorthand ahead of the scheme rules and
report the public-HTTPS correction instead.

The bare `git@host:org/repo.git` spelling took a different wrong turn: packaging
parses it as a direct reference named `git`, leaving `host:org/repo.git`, whose
`host` reads as a URL scheme and produced the generic HTTPS message. Both
spellings now share one message, as does the PEP 508 named form.

* docs: keep the root extension summary within its new budget

#4799 split the depth out of the module guides and added a size gate; the root
file's job is now orientation, and this branch had pushed it 192 bytes past the
soft limit. The manager transaction, source rules, and lock discipline are
already stated in full in the extensions guide, so the root keeps the one-line
orientation and points there instead of restating them.

feat(extensions): observe task lifecycle and system model calls (#4684)
* feat(extensions): observe task lifecycle and system model calls

PR 1 (#4636) gave extensions a middleware chain, and a middleware only sees
what passes through the agent graph. Two runtime surfaces stay invisible to
it: when a lead run or a subagent begins and ends, and the DeerFlow-owned
model calls made outside the graph. This slice adds both, with no new
Gateway surface -- routers, services, and the reference extension stay in
PR 3.

Contract (deerflow-extension-api 0.1.1)
---------------------------------------
Two contribution kinds join `middlewares` on the registry:
`task_lifecycle` (`on_task_start` / `on_task_stop`, receiving a `TaskInfo`
and a conservative `TaskOutcome` of completed / aborted / failed) and
`system_model_observer` (`on_system_model_call`, receiving a
`SystemOperationKind`, a `SystemModelRequest` snapshot, and a
`SystemModelResult` carrying either the response or the provider exception
plus a duration).

`SystemModelRequest.messages` normalizes to a tuple at construction. Goal
evaluation and memory extraction pass a message list while title generation
and summarization pass one prompt string, and a bare `str` already satisfies
`Sequence` -- without normalization an observer iterating `request.messages`
would silently walk characters. Copying also makes the frozen snapshot
immutable in fact rather than only by declaration, since observations may run
after the call site returns and keeps mutating its own list.

Registry marks and rollbacks become per-bucket and positional, so an
`install()` that fails after registering two different kinds cannot leave one
of them behind. `needs_task_store` now covers all three kinds: a deployment
that registers only lifecycle hooks still gets a task store.

Task lifecycle
--------------
The lead worker notifies start after the run has started and stop after
completion persistence and the completion hook, but before clearing the
finalizing barrier and publishing the stream end -- holding the barrier
across stop is what keeps a same-thread replacement run from overlapping this
task's lifecycle. Cancellation raised out of the stop notification is
deferred, not propagated in place, so a cancelled run still clears the
barrier and emits its end frame. A subagent with a parent `run_id` wraps its
execution in the same pair inside `finally`, reporting `parent_task_id` so a
delegation tree is reconstructable; a subagent without a `run_id` (embedded
client, standalone LangGraph Server) logs and skips rather than inventing a
parent. Contributors run in registration order inside one shared 3s budget
and every failure is logged and failed open.

System model calls
------------------
Four kinds cover the model calls the middleware chain cannot see: goal
evaluation, memory extraction, title generation, and summarization. Each site
reports both terminal paths without changing the provider exception the host
observes, short-circuits on `has_system_model_observers`, and passes the live
task store when the runtime has one (detached work gets an isolated store).
The sync summarization half stays unobserved on purpose -- it and its only
host caller are the sync side of an async-only runtime, so notifying there
would block a thread on a call site the host never reaches; the reason is
recorded at the call site.

The DeerMem backend must stay vendorable and cannot import the extension API,
so it reports through a new `MemoryCallbacks.on_memory_llm_result` host hook
that the DeerFlow-side callbacks translate into an observation.

Notification loop
-----------------
Extension resources must be touched on the loop that created them, but
subagents can execute on isolated loops and DeerMem runs on a worker thread.
The Gateway registers its serving loop before any runtime dependency starts
and resets it last through the exit stack, so every startup-failure and
cancellation path is covered. Awaited hooks raised on another loop are
dispatched across with `run_coroutine_threadsafe` and awaited under the same
budget; synchronous sites submit fire-and-forget work. Shutdown stops
accepting detached observations before the memory flush -- that flush runs on
a worker thread and can emit memory observations -- while keeping the loop
alive for awaited task hooks until run and subagent drain completes.

Tests
-----
`test_extension_task_lifecycle.py`, `test_extension_subagent_lifecycle.py`,
and `test_extension_system_model_calls.py` cover ordering, fail-open, budget
exhaustion, snapshot binding under a concurrent singleton replacement, the
loop-dispatch and shutdown-suspension paths, and both terminal paths at every
call site. `test_gateway_run_drain_shutdown.py` pins the stop-before-barrier
and drain ordering.

* fix(extensions): decide notification fail-open by origin, observe cancellation

`_notify_each` only guarded `Exception`, so a contributor letting a
`CancelledError` escape — an extension implementing an internal timeout with
cancellation, say — skipped its successors and reached the worker's
deferred-interrupt path, ending an otherwise successful run as cancelled.
Fail-open is about where a failure came from, not its base class: only a
genuine cancellation of the host task increments `Task.cancelling()`, so
propagate on that and contain everything else. `KeyboardInterrupt` /
`SystemExit` still propagate.

`observe_system_model_call` skipped observers on cancellation for the same
base-class reason, leaving goal / title / summarization silent on a terminal
path that is routine — interrupt/rollback admission and shutdown both cancel
the run task, with the provider tokens already spent. Awaiting observers there
is unreliable (a repeated cancel interrupts that await before any of them
runs), so report through the same non-blocking submission the synchronous
memory bridge uses, then propagate the cancellation untouched.

DeerMem keeps `BaseException` around its provider call, now with the reason
recorded: that path runs on a worker thread, where cancelling the awaiting
side never interrupts the running thread, so `CancelledError` cannot arrive
at all. Its host-hook wrapper narrows to `Exception` — only the hook's own
failures are non-fatal, and an observability path must not swallow a process
teardown signal.

* fix(extensions): warn on budget exhaustion, scope observer logs by task, propagate teardown

Review response on #4684:

- The memory observation bridge caught BaseException, which would swallow
  a teardown signal raised while dispatching; it now catches Exception,
  matching the boundary the DeerMem-side call site documents and tests.
- A notification-budget timeout raised mid-hook fell into the generic
  hook-failure path and logged an asyncio-internal traceback; it now logs
  a warning like the pre-hook budget skip, while a TimeoutError a
  contributor raises on its own stays classified as a hook failure.
- System model observer logs passed the operation kind as the task id,
  so log lines said "task goal/title/..."; they now carry the task
  scope id alongside the kind.

feat(channels): add Buzz (Nostr) channel connector (#4649)
* feat(channels): add Buzz (Nostr) channel connector

Adds a Buzz (https://github.com/block/buzz) channel so DeerFlow can join a
Nostr-relay workspace as a member: it answers @mentions in channels, replies
to DMs, and streams answers by editing one message in place.

  * app/channels/buzz_nostr.py — pure NIP-01 helpers: canonical event ids,
    BIP-340 signing/verification, chat/edit/auth builders, relay frames.
  * app/channels/buzz.py — BuzzChannel: one NIP-42-authenticated websocket,
    channel discovery (kind 39000) with one subscription per channel, live
    membership tracking (44100/44101), per-channel replay watermarks, and
    replies posted once then edited in place (kind 40003).
  * app/channels/buzz_run_policy.py — same-thread serialization, mirroring
    the Feishu precedent.

Inbound is gated in order: signature verification, self-drop, /connect
bind-and-return, pubkey allowlist, then mention / DM / mention-free /
thread-follow. Off by default; needs the new optional `buzz` extra
(coincurve, lazily imported), which detect_uv_extras resolves from
channels.buzz.enabled the same way it already handles channels.discord.

Two relay behaviours drove the design and are worth knowing when reviewing:
a global {"kinds":[9]} subscription receives nothing from buzz-relay and a
multi-value "#h" filter receives nothing either, so one REQ per channel is
required; and a single global `since` cursor skips quiet channels, so
watermarks are per channel.

* fix(channels): only publish assistant messages from the IM stream

`_accumulate_stream_text` decided what streamed `messages-tuple` payloads
become displayable text by rejecting ONLY payloads whose `type` contained
"tool", so it published everything else. DeerFlow writes hidden model
context into the messages channel as ordinary messages -- memory recall and
the rewritten user turn as hidden HumanMessages (DynamicContextMiddleware),
the `<durable_context_data>` block as another (DurableContextMiddleware) --
and LangGraph fans those state writes out on the messages stream, so they
reached every streaming IM channel as the assistant's reply.

Proved live on a Buzz relay: the connector published a `<memory>` fact block
and, in another run, a verbatim echo of the user's own inbound message.
Affects Feishu, Telegram, WeCom and Buzz; worst on Buzz, where each update
is an immutable public Nostr event that a corrective edit cannot unpublish.

Invert the filter to an allowlist of assistant message types. Two new pure
helpers keep it testable:

- `_stream_payload_type` resolves the type from both shapes the function
  already handles: the `model_dump()` shape the gateway emits, and
  LangChain's `to_json()` constructor shape whose own `type` is the literal
  "constructor" and whose class name is the tail of the `id` path.
- `_is_assistant_stream_type` matches "ai"/"assistant" by PREFIX, not
  substring -- ordinary words contain "ai" ("chain", "domain"), and a
  substring test would admit a foreign type name by accident.

The bare-`str` branch is removed: an untyped payload cannot be attributed to
the assistant, nothing in DeerFlow produces one (serialize_messages_tuple
always emits `[message_dict, metadata]`), and a runtime that emitted raw text
deltas would emit hidden context the same way. Per-message-id buffering and
merging are unchanged.

Tests pin both directions, including multi-chunk merging across one message
id, so the allowlist cannot silently kill streaming, plus an end-to-end

* chore(helm): bump config_version to 33 in chart values and README

config.example.yaml moved to 33 for the buzz channel block; the chart's
embedded config example and its README copy track it (config_version only
drives the outdated-config warning, per scripts/check_config_version.sh).

feat(extensions): add middleware plugin foundation (#4636)
* feat(extensions): add middleware plugin foundation

* fix(extensions): stop config resolution from masking extension loading

`create_app()` resolved the configured plugin list inside the fail-open
guard around `load_extensions()`. CI has no `config.yaml` (gitignored and
never generated by the workflow), so `get_app_config()` raised
`FileNotFoundError` there and was swallowed as an extension failure --
`load_extensions()` never ran at all, and the four `create_app()` tests in
`test_extension_app_loading.py` passed locally but failed on every runner.

Resolve the plugin list before the guard. Only an absent `config.yaml` is
tolerated, mirroring `_resolve_trace_enabled_for_app_construction()`:
`create_app()` runs at import time, and lifespan still performs strict
config loading before serving. A `config.yaml` that exists but fails to
parse or validate now propagates instead of being reported as an extension
failure -- reporting it as the latter silently dropped a `required: true`
extension rather than failing the boot.

Make the tests config-independent with an autouse `stub_app_config`
fixture, following the existing pattern in `test_gateway_lifespan_shutdown.py`,
and cover both new branches of the config-resolution boundary.

* fix(extensions): bind the run's extension snapshot through subagent delegation

The lead-agent path resolves one immutable loaded-extension snapshot per run
and binds it through task-store allocation and graph construction, but the
subagent path re-read the process-wide singleton at execution time. In
production both are the same object, yet a `set_loaded_extensions()` between
the lead run's start and a subagent's execution (test teardown, a future
hot-reload path) would let one run mix two extension generations — exactly what
the documented invariant exists to prevent.

The graph-build binding is a ContextVar scoped to synchronous construction, so
it has already exited by the time a tool delegates; the snapshot has to travel
through runtime context instead. The run worker publishes it under the
host-internal `EXTENSION_SNAPSHOT_CONTEXT_KEY` (written after the caller merge,
popped when the run has none, so a caller-supplied value is never
authoritative), `task_tool` reads it back through the type-checking
`resolve_run_extensions()`, and `SubagentExecutor` binds it at construction.

Callers outside the Gateway run path — embedded `DeerFlowClient`, standalone
LangGraph Server — install no snapshot and keep the existing
`get_loaded_extensions()` fallback.

* refactor(extensions): defer the ordering table by call, not by a lying tuple

`CORE_ORDERING_CONSTRAINTS` was a `tuple` subclass that overrode only
`__iter__` and resolved into a class-level `_resolved` side channel. A tuple
cannot populate its own storage after construction, so the instance stayed the
empty tuple it was built as: `len()` was 0, `bool()` was False, `in` was always
False, indexing raised, slicing and `reversed()` came back empty, and it
compared unequal to the plain tuples tests substitute for it — all while
iteration yielded the real constraints. Only `assert_ordering` consumed it, and
only by iterating, so the split went unnoticed.

The sibling `_AnchorTable(dict)` uses the same idea soundly because dict is
mutable: `self.update()` fills the real storage, making every inherited
operation correct. That trick does not survive the port to an immutable type.

Replace it with `core_ordering_constraints()`, matching how `stack.py` defers
the same kind of table via `_anchors()`. The deferral is kept — it is about
dependency direction, not just cycles: `extensions/` is the layer the
middleware layer calls into, so a module-scope `agents.middlewares` import here
points the dependency backwards and closes a cycle as soon as any middleware
imports something under `extensions/` at module level. Resolution stays at
`assert_ordering` time, which already runs inside the middleware builder.

Tests pin both halves: the returned value is a plain tuple whose len/bool/
membership/indexing/reversal/equality agree with iteration, and a subprocess
probe asserts importing `extensions.ordering` does not load the middleware
layer while calling the function does.

feat(sandbox): add Tenki cloud sandbox provider (#4382)
* feat(sandbox): add Tenki cloud sandbox provider

Adds deerflow.community.tenki, a SandboxProvider backed by Tenki cloud
microVMs, alongside the existing e2b_sandbox / boxlite / aio_sandbox
backends. Selected via `sandbox.use: deerflow.community.tenki:TenkiSandboxProvider`
(resolved by class path, so the change is purely additive).

The full Sandbox contract is implemented — execute_command plus
read/write/update/download_file and list_dir/glob/grep — with file ops run
as busybox-portable shell commands (cat / find / grep / chunked base64),
reusing deerflow.sandbox.search, mirroring e2b_sandbox and boxlite. Tenki's
SDK is synchronous, so unlike boxlite there is no event-loop bridge.

Tenki sandboxes run as an unprivileged user with /mnt root-owned, so the
/mnt/user-data virtual prefix is remapped under the writable home dir (like
e2b_sandbox); the provider also best-effort sudo-symlinks /mnt/user-data to
that home dir so agent shell commands using the literal path still work.
Sandboxes are pooled per (user, thread) with warm reclaim, a replica cap,
and an idle reaper via the shared WarmPoolLifecycleMixin. Transient
transport blips get one bounded retry; terminal session errors evict and
recreate.

Only the stable Tenki surface is used (create/terminate + exec/shell/fs) —
no volumes, snapshots, or template builds — so any stock base image works.
The tenki-sandbox SDK is an optional extra (deerflow-harness[tenki]) and is
imported lazily, so a default install and every other provider are
unaffected.

Tested: unit suite runs in CI without tenki-sandbox installed; a live
integration test and full-surface e2e were verified against real Tenki
sandboxes.

* fix(sandbox): remove unsafe auto-retry from Tenki exec

Pre-merge review caught that the transient-transport retry sat at the
universal _exec layer, so it retried every operation — execute_command and
base64 file-write chunks included. gRPC has no exactly-once guarantee: a
"socket closed" ack-drop after the server already ran the op means the retry
runs it twice, double-firing command side effects and duplicating a write
chunk mid-file (silent binary corruption on multi-chunk writes).

exec is not idempotent, so it must not be auto-retried. Reverts to the
boxlite/e2b behavior: a transient error surfaces to the caller (returned as
text by execute_command, raised by the file ops); a terminal session error
still evicts the sandbox so the next acquire rebuilds it. Verified live
end-to-end across 31 edge cases (empty/binary/unicode/chunk-boundary files,
shell-metachar content, error paths, list/glob/grep, warm-pool reclaim,
concurrency).

* fix(sandbox): address Tenki provider review feedback

- Use Tenki's native sandbox.fs API for all file transport (read_text,
  read_bytes, write_stream, mkdir) instead of cat/chunked-base64 over shell.
  Uploads stream in 1 MiB frames; append is read-modify-write because the
  write stream has no append mode (same approach as community/e2b_sandbox).
- download_file streams via fs.read_stream and enforces the 100 MB cap on
  bytes actually received, closing the TOCTOU window between the old
  wc -c size probe and the read.
- list_dir/glob/grep report paths back under /mnt/user-data instead of the
  sandbox-internal home dir, so results feed straight into the file APIs.
- Create with wait=False and await wait_ready() here: create(wait=True)
  raises with the session handle still inside the SDK, leaking a running
  microVM this provider could never terminate.
- Configure the sandbox lifetime (max_duration, default 4h) and expose
  sticky; without it Tenki reaps a reused thread's sandbox after ~30 min.
- close() terminates before marking the adapter closed and re-raises real
  failures, so a failed termination stays retryable instead of silently
  leaking a billed microVM; an already-gone session still counts as closed.
- Bump the optional extra to tenki-sandbox>=0.4.0 and commit backend/uv.lock.

* fix(sandbox): scope tenki grep() glob filter to its directory prefix

Mirrors #4168, which fixed the same defect in the E2B provider. The tenki
adapter reduced a directory-scoped pattern like "src/*.js" to its basename
before filtering, so the search silently broadened to every matching-extension
file in the tree. Post-filter grep's hits through path_matches() against the
path relative to the search root, the same way glob() already does, so both
agree on what a directory-scoped pattern means.

* fix(sandbox): address Tenki provider review — eviction, id width, write lock, grep -H

Four fixes from the upstream review:

download_file no longer swallows terminal transport errors. The broad
`except OSError: raise` re-raised ConnectionError/BrokenPipeError/EOFError
(all OSError subclasses that _is_terminal_failure treats as terminal) before
_note_failure ran, so a session that died mid-download was never evicted. Only
our own EFBIG size-cap now passes through without eviction.

Sandbox id widened from 32 to 64 bits (`[:8]` to `[:16]`), matching
community/e2b_sandbox. The warm pool is keyed by this id with no full-seed
fallback, so a collision could let one user reclaim another's parked sandbox on
a multi-tenant gateway.

_fs_op now holds the lock across the op, not just the fs lookup, so concurrent
calls on the same sandbox serialise over the SDK's shared connection. The
eviction callback runs after the lock is released to avoid a lock-order
deadlock with the provider. The append read-modify-write is serialised by a
dedicated _write_lock so two concurrent appends can't clobber each other.

grep passes -H so a search whose path resolves to a single file still prints
the filename; without it the file:line:text unpack dropped every match.

* fix(sandbox): address Tenki provider review round 2

- validate config `environment` at load time (_validate_extra_env) so a bad
  key fails fast instead of surfacing as an SDK error mid-command
- document the deliberate lock decision in download_file: the instance lock is
  dropped before streaming so a 100 MB download can't block every other tool;
  terminal transport errors still evict via _note_failure
- tighten the terminal-error comment to note ConnectionError/BrokenPipeError/
  EOFError are also treated terminal via isinstance
- document TenkiSandboxProvider in backend/AGENTS.md (provider detail, warm-pool
  destroy hook, community provider list)
- add a commented Tenki block to config.example.yaml for parity with AIO/BoxLite
- tests: config env validation, grep -F/case-sensitive flags, glob include_dirs,
  list_dir max_depth, bootstrap-failure warning branch

* fix(sandbox): make Tenki bootstrap non-interactive and time-bounded

The create-time bootstrap runs under the per-scope acquire lock, so a hang
would stall acquire for that scope indefinitely:
- use `sudo -n` so a password-requiring sudoers entry fails fast (swallowed by
  the existing `|| true`) instead of blocking on a tty password prompt
- pass a timeout to the bootstrap `remote.exec` so any other stall drops to the
  existing warning path rather than wedging acquire

Best-effort by design; the file APIs still work via the home remap on failure.

* test(sandbox): pin Tenki bootstrap timeout to its actual value

Assert bootstrap["timeout"] == _BOOTSTRAP_TIMEOUT instead of `is not None`, so
a regression to timeout=0 (treated as no timeout by some SDKs) or an unrelated
value is caught rather than passing a weaker non-None check.

feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel (#4292)
* feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel

Add a restart-required database.checkpoint_channel_mode ("full" default,
"delta") that stores the messages channel via LangGraph 1.2 DeltaChannel,
cutting checkpoint storage from O(n^2) to O(n) for append-only history.
Existing full checkpoints seed delta state transparently; no data migration.

- config: mode schema + freeze-on-first-use with
  CheckpointModeReconfigurationError; mode marker persisted in checkpoint
  metadata; unsafe delta->full downgrade rejected fail-closed with
  CheckpointModeMismatchError (run-level error, failed state read)
- state: delta message state schema; CheckpointStateAccessor centralizes
  materialized reads for all consumers (threads API, branches,
  regeneration, compaction, state updates, memory, goal workers)
- runtime: raw writers (run durations, interrupted title, thread goal)
  parent their checkpoints to the checkpoint they derive from, preserving
  delta ancestry; rollback forks the pre-run lineage through a state
  mutation graph with Overwrite restores; InMemorySaver delta-history
  override delegates to the base walk (fixes dropped first write after
  migration, also present upstream)
- tests: conformance suite over {memory, sqlite, postgres} covering
  migration replay, stable message IDs, storage shape and writer
  preservation; conftest fixture isolates the frozen mode between tests;
  stale config fakes refreshed
- ci: backend unit tests gain a postgres service

* fix(checkpoint): close materialization gaps in goal flow, guard public factory

- Route goal-continuation message reads through CheckpointStateAccessor:
  raw channel_values reads see the delta sentinel in delta mode, which
  disabled goal continuation (stand_down=no_durable_end_of_turn) after
  durable assistant turns. Raw tuples remain for tuple-only metadata
  (checkpoint id, pending_writes).
- Reject checkpoint_channel_mode='delta' + checkpointer in
  create_deerflow_agent at construction: factory-built persisted graphs
  bypass mode-marker injection and the fail-closed gate, reproducing
  silent mixed-mode state loss. Delta without persistence stays allowed.
- Import the postgres saver lazily (pytest.importorskip in the fixture)
  so the documented default install collects the suite; add a CI job
  running pytest --collect-only on uv sync --group dev without extras.
- Fix test_checkpointer fallback test to patch get_app_config at its
  use site (provider module), making it deterministic when a local
  config.yaml selects a persistent backend.

* fix(gateway): preserve extension-owned channels in state mutations, bump config version

- build_state_mutation_graph / build_checkpoint_state_mutation_accessor
  accept an explicit state_schema; branch and POST /state now compile the
  mutation graph from the thread's effective schema
  (graph_state_schema on the assistant graph). The base-ThreadState
  fallback silently discarded channels contributed by custom
  AgentMiddleware.state_schema on branch (data loss) and returned a
  false-success 200 on POST /state.
- POST /state validates values keys against the mutation graph's
  channels and rejects unknown fields with 422 instead of ignoring
  them; reducer detection covers extension channels
  (BinaryOperatorAggregate or DeltaChannel) so Overwrite replace
  semantics work for middleware reducers in both modes.
- Endpoint regression: custom AgentMiddleware.state_schema value
  survives branch, updates through POST /state, and an unknown field
  receives 422.
- config_version 26 -> 27 for the new database.checkpoint_channel_mode
  (example, Helm chart values + README, support-bundle fixture), so
  existing installs get the outdated-config warning and
  make config-upgrade merges the field; covered by a test driving the
  real example file and the real config-upgrade script.

* fix(gateway): resolve assistant schema via one boundary, copy branch reducer values with Overwrite

GET /threads/{id}/state now resolves the thread's assistant_id through a
single reusable boundary (thread metadata -> assistant_id -> effective
graph), so channels contributed by a custom AgentMiddleware.state_schema
are materialized instead of dropped by the default lead schema. POST
/state uses the same boundary instead of resolving the schema ad hoc.

Branch writes wrap every copied reducer channel in Overwrite (derived
from the effective mutation graph: BinaryOperatorAggregate + DeltaChannel),
not just messages, so already-aggregated values are never re-merged.

Regression tests use a real AgentMiddleware.state_schema with a
non-identity reducer in both full and delta modes: GET /state returns the
extension value, POST /state replaces it, branch preserves it
byte-for-byte; the unknown-field 422 is a separate assertion.

* refactor(checkpoint): collapse read-path round-trips and ship dual-mode parity tests

Address review round 4 on PR #4292:

- Push ahistory/history limit through Pregel into checkpointer.alist
  (SQL LIMIT) instead of materializing all rows and breaking in Python
- Fold the read-side mode-compat gate onto the returned snapshot's
  metadata; only writes keep the pre-write tuple fetch (fail-closed)
- Cache factory-built accessor graphs per (assistant_id, mode) with
  factory-identity revalidation; state reads no longer build a lead
  agent per request
- get_thread: one snapshot fetch + one raw pending_writes fetch on the
  resolved checkpoint (post-checkpoint __error__ writes never surface
  in snapshot.tasks; verified empirically)
- DeerFlowClient.get_thread: single checkpointer.list walk collects
  pending_writes per checkpoint instead of N get_tuple calls
- InMemorySaver delta-history patch: stand-down when the upstream
  override disappears, try/except guard, validated-version warning,
  guard tests
- make_lead_agent mode precedence: first freeze is owned by app_config
  (client-supplied configurable key ignored); once frozen, injected
  key/app_config must match or fail closed
- Rollback: lock in non-message channel restoration via fork
  inheritance with a dedicated reducer-channel test
- Add tests/test_threads_checkpoint_mode.py and
  tests/test_gateway_checkpoint_mode.py referenced by AGENTS.md and
  the PR validation section: lifecycle parity (memory + sqlite),
  per-step blob-count storage guard, gateway endpoint parity

Counted-saver tests pin checkpoint round-trips for aget/ahistory so
these regressions cannot silently return.

* fix(checkpoint): precise mode-mismatch HTTP mapping, gate E2E, and accessor resilience

- threads router: map CheckpointModeMismatchError to 409 (with cause and
  thread id) and CheckpointModeReconfigurationError to 503 across all state
  endpoints instead of swallowing both into a generic 500
- gate coverage: seed a real delta checkpoint into AsyncSqliteSaver and
  assert aget/aupdate/ahistory fail closed; assert 409 at the HTTP boundary
  through the real route stack
- rollback: compile the restore mutation graph with the thread's effective
  state schema per the build_state_mutation_graph contract
- inheritance contract locks: rollback and manual compaction preserve
  middleware-contributed channels via checkpoint fork cloning
- services: revalidate the accessor-graph cache against app_config identity
  so config.yaml hot-reloads never serve a stale compiled graph
- services: degrade full-mode state reads to raw checkpointer reads when the
  agent factory is unavailable (delta gate still applies; delta mode has no
  fallback)
- deps: override websockets==16.0 (langgraph-sdk 0.4.2's <16 pin silently
  downgraded 16.0 -> 15.0.1; pin is not grounded in any API incompatibility)
  and bump the langchain lower bound to what the lockfile actually resolves

* fix(checkpoint): include anchor checkpoint in degraded history walk + cover get_thread

- _RawCheckpointReadAccessor.ahistory: alist(before=...) is exclusive while
  pregel's get_state_history treats config.checkpoint_id as the inclusive
  start; fetch the anchor explicitly so both read paths paginate identically
- extend the degraded-path gateway test: GET /thread returns raw values, and
  POST /history with before starts at the anchor checkpoint

* fix(gateway): preserve degraded checkpoint timestamps

* fix(gateway): harden degraded checkpoint access

* fix(gateway): resolve assistants for checkpoint reads

feat(browser): add agentic browser control (#4187)
* feat(browser): add agentic browser control

* fix(frontend): format browser view changes

* fix(browser): keep browser optional and isolate sidecar layout

* fix(browser): address PR review security and IME findings

- Nginx: add a browser-stream WebSocket location before the generic
  /api/threads regex so Live upgrades instead of downgrading to HTTP
  (both nginx.conf and nginx.local.conf).
- Ownership: require an existing owned thread for the WS stream and REST
  navigate, and tear down the browser session on thread deletion so a
  later caller cannot reuse a retained page/cookies by guessing the id.
- SSRF: enforce the URL policy at the browser request boundary via a
  context-level route guard covering redirects, popups, iframes, and
  subresources (skipped for CDP-attached Chrome).
- IME: skip key forwarding while a composition is active so confirming a
  CJK candidate with Enter no longer submits the remote page form.

Adds regression tests for the request guard, session teardown on delete,
and the composing-Enter key decision.

* fix(frontend): smooth streaming in long tool threads

* Revert "fix(frontend): smooth streaming in long tool threads"

This reverts commit f0462516eabe77f138d4027ea1c714fb226683cf.

* fix(browser): address review security and lifecycle findings

- Reject cross-origin WebSocket upgrades on the live browser stream
  (Origin allow-list reuse of CORS/same-origin helpers) to close a
  WS-CSRF hole, and fail closed when the ownership store is absent.
- Warn when a CDP-attached session runs with the SSRF request guard
  off, and drop the unreachable CDP screencast teardown dead code.
- Read browser session launch config from a single canonical source
  (browser_navigate) so it is deterministic regardless of call order.
- Bound per-thread Chromium accumulation with idle-timeout eviction
  and an LRU max-sessions cap.
- Reset the Live reconnect counter on a successful open so the stream
  can't permanently stall after the cumulative attempt cap.

* fix(frontend): reduce long tool thread render stalls

Reuse stable historical message groups during streaming, defer heavy Markdown and browser previews, and lazy-decode message images.

* fix(browser): keep live control responsive during continuous input

Why: Manual browser control felt laggy — a physical click ran the remote
Playwright click three times and each non-move input synchronously awaited a
JPEG screenshot, so events queued behind capture (queue wait up to ~237ms).
The first async attempt used a trailing-edge debounce, which froze the visible
page until a wheel/keyboard gesture stopped ("scroll finishes, then it jumps").

What:
- Frontend forwards one `click` per physical click instead of also emitting
  `down`/`up`, so the remote page is not clicked twice per gesture.
- Backend detaches live-frame capture from input dispatch: non-move actions
  start a rate-limited background refresh loop (leading frame + bounded cadence)
  that keeps emitting frames while input continues and never blocks dispatch.
- Add regression tests: input dispatch no longer awaits the screenshot, rapid
  inputs coalesce, and continuous input keeps refreshing before it stops.

Scenarios: Verified in the live Browser panel — a single click completes in
~57ms (was blocked behind a 171ms capture), and a 1.14s sustained wheel gesture
renders ~7 frames throughout the scroll instead of one frame after it ends.

* fix(browser): harden worker and session lifecycle

* fix(browser): address latest review feedback

* fix(frontend): preserve optimistic new-chat message

* test(e2e): preserve mocked message run ids

* fix(browser): address capability review feedback

feat(trace): add agent observability with Monocle (#4024)
* Add Monocle tracing

Enable Monocle (OpenTelemetry tracing for LLM apps) with one setup call plus the monocle_apptrace dependency. setup_monocle_telemetry auto-instruments the frameworks already in use and writes traces to .monocle/. Additive; no changes to application logic.

* Config-gate Monocle telemetry in the Gateway lifespan

Addresses review on #4024: moves setup_monocle_telemetry out of agents/__init__ import time into the Gateway lifespan, gated by MonocleTracingConfig (MONOCLE_TRACING env, default off). Warns on the Langfuse/global-OTel-provider conflict and relies on monocle_apptrace's own duplicate-setup guard and existing-provider attach. Pins monocle_apptrace>=0.8.8 (+ uv.lock), adds .monocle/ to .gitignore, adds tests (default-off / toggle-on / no import-time setup), and documents exporters, Okahu, and the VS Code viewer in README, config.example.yaml, and backend/AGENTS.md.

* Clarify Monocle/Langfuse single-provider guidance

Make the docstring, warning, and AGENTS.md consistent with the README: only one library can own the global OpenTelemetry provider; Monocle initializes at startup before Langfuse's per-run handler, so enabling both drops Langfuse's spans — enable one OTel tracer (LangSmith, a callback, coexists fine).

* Address review: optional extra, exporter validation, off-box warning, tests

Responds to the second review round.

- Make monocle_apptrace an optional extra (deerflow-harness[monocle], re-exposed
  as deer-flow[monocle]) following the boxlite/tui precedent, so a default
  install no longer pulls the OpenTelemetry stack. It stays pinned in the dev
  group for the tracing tests, and enabling MONOCLE_TRACING without the extra
  raises a clear install error.
- Warn loudly at startup whenever any exporter other than `file` is configured,
  since those move prompts, tool inputs/outputs, and completions beyond the
  local .monocle/ directory.
- Validate MONOCLE_EXPORTERS against the known exporter names and require
  OKAHU_API_KEY when okahu is selected, mirroring the Langfuse pattern.
  Validation runs from Monocle's own init (not validate_enabled) so a config
  typo can never fail agent runs; errors surface at Gateway startup instead.
- Grow the tests from 5 to 13: caplog coverage for the Langfuse-conflict and
  off-box warnings, exporter validation cases, a stronger import-time
  regression that asserts the global TracerProvider is not replaced, and a
  subprocess double-invoke test exercising the real check_duplicate_setup.
- Docs: config.example.yaml block retitled to a dedicated tracing header;
  README documents the [monocle] install and scopes tracing to Gateway runs.

* docs: align Monocle README section with the other tracing providers

Lead with what Monocle is and captures, drop the install step (the dev
group already ships monocle_apptrace via uv sync; unusual installs get
the RuntimeError), and point the missing-package error at the repo-native
command (uv sync --extra monocle / deerflow-harness[monocle]).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Address review: verified Langfuse coexistence, lifespan test, scope docs

Responds to the third review round.

The Langfuse conflict claim was wrong, verified empirically against langfuse
4.5.1 in both init orders: whichever library initializes second reuses the
existing global TracerProvider and attaches its own span processor, so neither
side loses spans. Dropped the warning and its tests, corrected the README,
AGENTS.md, and config.example.yaml statements, and pinned the verified behavior
with test_coexists_with_langfuse (real monocle + real langfuse in a subprocess,
no mocks). One honest caveat documented: both processors see all spans, so
Monocle's exporters also capture Langfuse's spans when both are enabled.

Also from the review:
- Document the Gateway-only scope in AGENTS.md: the lifespan is the sole call
  site, so the embedded DeerFlowClient and TUI are not instrumented; embedded
  users call setup_monocle_tracing_if_enabled() themselves.
- Add test_gateway_lifespan_initializes_monocle pinning the lifespan wiring.
- Comment why MonocleTracingConfig.is_configured is intentionally coarser than
  LangSmith/Langfuse (composite validation lives in validate() at startup).
- Note that monocle_exporters_list takes the comma-separated string as-is.
- Module-level importorskip("monocle_apptrace") so minimal installs collect
  the test module cleanly.

* docs: reword Monocle intro sentence

* fix(tests): run the import-time regression in a subprocess

test_no_import_time_setup deleted deerflow.agents* from sys.modules and
re-imported to force __init__ to re-execute. The re-import creates new module
objects, and restoring the old sys.modules entries afterwards leaves the parent
package's attribute bindings pointing at the new ones, so any later test that
resolves a deerflow.agents.* dotted path (monkeypatch.setattr in
test_summarization_middleware, test_thread_data_middleware, and others) failed
with "module 'deerflow.agents' has no attribute ...".

Run the check in a subprocess instead: the import is genuinely fresh, the
assertion is stronger (the provider must still be the SDK-less proxy, proving
nothing was installed at any point), and no module identity leaks into the
rest of the suite.

* Address review: console warning scope, embedded hint, honest naming, doc alignment

Responds to the post-approval review round:

- Scope the off-box exporter warning to the remote exporters (okahu, s3,
  blob, gcs): console writes to local stdout and no longer trips it.
  config.example.yaml's data-handling note now distinguishes file /
  console / remote likewise.
- Rename MonocleTracingConfig.is_configured to is_enabled so the boolean
  reads as what it checks; the exporter-dependent credential check stays
  in validate(), run at Gateway startup.
- Hint on the embedded path: build_tracing_callbacks() logs a debug line
  when MONOCLE_TRACING is set but setup never ran in this process, so
  embedded DeerFlowClient/TUI users are not left with silent no-op
  tracing. Backed by a process-global setup flag.
- Re-export setup_monocle_tracing_if_enabled from deerflow.tracing,
  matching the package convention.
- Note the deliberate fail-open-at-startup contrast with
  LangSmith/Langfuse in the lifespan, and the OTel SDK-internals
  dependency in the coexistence test.
- Test hygiene: clear MONOCLE_* env in the tracing config/factory
  fixtures; reset the setup flag in the monocle test fixture; reword the
  README Langfuse-spans claim as the shared-provider inference it is.
- Document that .monocle/ trace files are never rotated or cleaned up.

* fix(tests): pin the factory logger level in the embedded-hint tests

configure_logging() from earlier tests in the full suite pins an explicit
INFO level on the logger hierarchy, so a root-level caplog.at_level(DEBUG)
never sees the factory's debug hint. Scope caplog to
deerflow.tracing.factory so the test is independent of suite ordering.

* Address review: co-export disclosure, lifespan failure test, exporter parse dedup

- Off-box warning now notes that Langfuse's spans are exported too when
  both providers are enabled and share the global OTel provider; pinned
  both ways by tests.
- Pin the lifespan fail-open contract: a raising Monocle setup is logged
  and the Gateway keeps serving (pragma dropped now that the path is
  exercised). README notes a config error is reported at startup and
  tracing stays off until restart.
- Hoist exporter parsing into MonocleTracingConfig.exporter_list so
  validate() and the off-box warning cannot diverge, and note the
  upstream coupling on the exporter allow-list.
- Reduce config.example.yaml's Monocle block to a pointer; the capture,
  retention, and data-handling detail lives in README's Monocle section.

feat(sandbox): warm pool for boxlite (#3951)
* feat: add boxlite SDK as harness dependency

* test: add fake SimpleBox fixtures for BoxLite warm pool tests

* feat: add deterministic sandbox_id and warm pool fields to BoxliteProvider

* feat: pass deterministic sandbox_id to SimpleBox name

* feat: warm pool lifecycle — park on release, reclaim on acquire

- release(): parks VMs in _warm_pool with timestamp instead of closing
- _reclaim_warm_pool(): health checks warm boxes via echo ok
- acquire(): tries warm pool reclaim before creating new boxes
- Deterministic sandbox_id ensures thread isolation

* feat(boxlite): idle reaper, replica enforcement, warm-pool shutdown/reset

- Task 6: idle reaper daemon thread destroys expired warm-pool boxes
- Task 7: replica enforcement evicts oldest warm-pool box when at capacity
- Task 8: shutdown() stops idle checker first, destroys all boxes (active+warm);
  reset() clears warm pool

Tests: 17 passed (4 new: idle reaper, replica enforcement, shutdown, reset)

* fix(boxlite): harden warm pool lifecycle races

* docs(boxlite): document warm pool configuration

* fix(sandbox): log warning when evicting oldest warm box is failed

Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

* fix(boxlite): stop provider lifecycle on reset

* fix(boxlite): make runtime an optional dependency

* test(boxlite): remove unused warm pool lookup

* docs(boxlite): clarify optional runtime support

* refactor: extract shared WarmPoolLifecycleMixin for sandbox warm-pool lifecycle

Introduce deerflow.community.warm_pool_lifecycle.WarmPoolLifecycleMixin
owning idle-checker loop, warm-pool expiry, oldest-warm eviction,
replica counting, and soft-cap logging. Move AioSandboxProvider and
BoxliteProvider onto the mixin; keep AIO active-idle cleanup local and
delegate only warm-pool expiry to the shared helper.

BoxliteProvider also gains:
- Prefixed box names (deer-flow-boxlite-*) for startup orphan reconciliation
- _reconcile_orphans() adopting surviving boxes from a prior process
- Pinned timeout forwarding: command timeout now bounds both BoxLite
  SDK exec(timeout=...) and the loop bridge .result(timeout)
- reset() reworked as lightweight registry clear (boxes -> warm pool,
  no close, no idle-reaper stop, no loop close) so reset_sandbox_provider()
  config switches are safe; shutdown() remains the teardown path

Backward-compatible: AIO DEFAULT_IDLE_TIMEOUT/DEFAULT_REPLICAS/
IDLE_CHECK_INTERVAL stay importable; Boxlite IDLE_CHECK_INTERVAL
stays monkeypatchable.

feat: add scheduled tasks MVP (#3898)
* feat: add scheduled tasks MVP

* fix: harden scheduled task execution semantics

* feat(scheduled-tasks): preset-driven schedule form with timezone and live preview

Replace the raw cron input with a preset Select (hourly/daily/weekly/monthly/custom)
plus structured inputs (time picker, weekday toggles, day-of-month), datetime-local
for one-time tasks, a timezone selector defaulting to the browser timezone, and a
live human-readable preview. Reuses one ScheduledTaskScheduleInput for create and
edit; backend contract unchanged; zero new deps (pure Intl + DST-safe offset helpers).

* feat(scheduled-tasks): full-page i18n + recipe templates + E2E locale pin

Localize the rest of the scheduled-tasks page (filters, detail pane, actions,
edit form, run list, enum values) via t.scheduledTasks.* in en/zh. Add four
built-in recipe templates (GitHub Trending, news digest, issue triage, weekly
report) exposed as a chip row that pre-fills title + prompt + schedule. Pin
Playwright locale to en-US so E2E selectors stay stable against i18n. No backend
change, no new deps.

* fix(scheduled-tasks): idempotent 0003 migration, update head constants, future-date once test

Merge with main surfaced three CI failures:
- 0003_scheduled_tasks create_table collided with legacy test seeds that
  build from full metadata; guard with inspector.has_table so the revision
  no-ops when the table already exists (0004/0005 are already idempotent via
  _helpers.py).
- persistence bootstrap concurrency/regression tests pinned HEAD to main's
  0002_runs_token_usage; bump to the new head 0005_scheduled_task_thread_nullable.
- once-task router test used a fixed past run_at and tripped the
  must-be-in-the-future validation; use a future date.

* address review: ok-check, 502 for trigger failure, mock fields, migration filename, doc fences

- fetchThreadScheduledTasks now checks response.ok like the other fetchers.
- trigger endpoint returns 502 (not 409) when dispatch fails outright, so
  clients can distinguish a real conflict from a server-side failure.
- E2E mock normalizes scheduled-task objects with context_mode/last_thread_id
  and nullable thread_id, matching the backend contract the UI renders against.
- Rename 0002_scheduled_tasks.py -> 0003_scheduled_tasks.py to match its
  revision id (file was renamed in spirit already; filename now follows).
- CONFIGURATION.md: close the Tool Groups yaml fence and drop the stray fence
  after the Scheduler notes so the sections render correctly.

* fix(scheduled-tasks): harden lease, poller, config, and frontend UX after review

* fix(scheduled-tasks): harden run lifecycle, overlap skip, non_interactive gating, and DST conversion after review

- defer a once task's terminal status to the run-completion hook; the task
  stays running until the real outcome, and a startup sweep cancels once
  tasks orphaned by a crash (launch-time 'completed' could stick forever)
- record interrupted runs as a distinct 'interrupted' run status with a
  readable message; an interrupted once task ends 'cancelled', not 'failed'
- enforce overlap_policy=skip for fresh_thread_per_run via an active-run
  pre-check (same-thread ConflictError can never fire across fresh threads)
- protect terminal run statuses from the late launch-path 'running' write
- honor context.non_interactive only for internally-authenticated callers;
  arbitrary clients can no longer strip ask_clarification
- fix DST-stale timezone offset in zonedLocalToUtcIso by re-deriving the
  offset at the resolved instant (once tasks fired an hour late around
  spring-forward and the create->edit round-trip diverged)
- drop dead ScheduledTaskRunRepository.update_by_run_id; share one Gateway
  API error helper between channels and scheduled-tasks frontends

* fix(scheduled-tasks): close review round-3 gaps in guards, concurrency, and API ergonomics

- scrub internal-only context keys (non_interactive) from the assembled run
  config for non-internal callers: gating body.context alone left the same
  key smuggle-able through the free-form body.config copied verbatim by
  build_run_config
- guard update_after_launch with protect_terminal so the launch bookkeeping
  write cannot clobber a once task already finalized by a fast-failing run's
  completion hook (parent-row sibling of the run-row guard)
- reject a manual trigger while the task has an active run (409) instead of
  launching a duplicate concurrent run on fresh_thread_per_run
- re-arm a terminal once task to enabled when PATCH pushes run_at into the
  future; previously the endpoint returned 200 with a next_run_at that could
  never be claimed
- make max_concurrent_runs a real global cap: each poll claims only into the
  remaining budget of active (queued/running) scheduled runs
- paginate GET /scheduled-tasks/{id}/runs (limit<=200, offset) and push the
  thread filter of /threads/{id}/scheduled-tasks into SQL
- stamp context.user_id on scheduler-launched runs, matching IM channels, so
  user-scoped guardrail providers see the owning user

feat(gateway): add redis stream bridge (#3191)
* feat: add redis stream bridge

* Potential fix for pull request finding

Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

* fix(gateway): address redis stream bridge review

Redis was imported eagerly through deerflow.runtime and declared as a hard dependency, which made memory-only installs load redis.asyncio at startup and left the lazy factory import ineffective. Move redis behind an optional extra, remove the public eager re-export, and keep make_stream_bridge as the only runtime import path with an actionable install hint when the extra is missing.

Because Docker deployments now default the stream bridge to Redis via DEER_FLOW_STREAM_BRIDGE_REDIS_URL, install the redis extra explicitly in Docker/dev container flows and teach the local uv-extra detector to infer redis from both stream_bridge.type and the Redis URL env var. This keeps Docker working while preserving slim non-Docker installs.

Harden the Redis bridge by batching XREAD replay, replacing brittle ResponseError string matching with a single fallback to 0-0 for malformed Last-Event-ID values, documenting connection/retention/fail-hard behavior, and adding fake plus opt-in real Redis coverage for XADD/XREAD, replay, invalid IDs, and MAXLEN trimming.

* fix(config): bump config version for stream bridge

* fix redis stream bridge terminal handling

* fix: repair uv.lock, format redis.py, and align Dockerfile extras test

The uv.lock file was missing a closing bracket for the redis extras
section, redis.py had a formatting issue caught by ruff, and the
Dockerfile extras test did not account for the hardcoded --extra redis
flag.

feat(tui): Hermes-like terminal workbench (deerflow) backed by DeerFlowClient (#3760)
* feat(tui): add Hermes-like terminal workbench backed by DeerFlowClient

Implements the `deerflow` TUI from RFC #3540: a terminal-native, embedded
workbench over the existing harness (no Gateway/frontend/nginx/Docker), built
Python-native with Textual and learning UX patterns from tao-pi.

Architecture — every layer except the Textual app is pure and unit-tested:
- view_state.py: ViewState + reduce(state, action), the testable heart
- runtime.py: StreamEvent -> reducer actions (pure translate + threaded driver)
- message_format / command_registry / input_history / render / theme: pure
- app.py: Textual App; runs the sync DeerFlowClient.stream() on a worker thread
  and marshals actions back to the UI thread. Slash command palette, model and
  thread modal pickers, ↑/↓ history, Ctrl+C interrupt, TTY-aware fallback.
- cli.py: pure launch-mode planning + headless --print/--json + `deerflow`
  console script (textual is an optional [tui] extra; degrades to headless help)

Web UI visibility (the RFC's key decision): persistence.py writes a threads_meta
row under the local default user into the same DB the Gateway reads, so terminal
sessions appear in the Web UI sidebar without running the Gateway. Best-effort,
no-op on the memory backend; all DB work on one long-lived background loop.

Tests: 95 TUI tests — pure layers via pytest, app/palette/overlays via Textual's
pilot harness with a fake session, and a threads_meta read/write round-trip.
ruff clean; respects the harness->app import boundary. Docs: backend/docs/TUI.md
plus CLAUDE.md/README updates and preview screenshots.

* fix(tui): de-duplicate streamed assistant text and tool cards; keep Tab in composer

Self-test surfaced three issues, all root-caused to consuming non-strict
streaming from DeerFlowClient (proven by the client's own
test_dedup_requires_messages_before_values_invariant, which shows the client can
re-emit a message id's full content twice):

- Assistant text was doubled (e.g. "answer answer") because the reducer blindly
  concatenated same-id deltas. Now merges by content: a re-send or cumulative
  snapshot replaces; only genuine increments append.
- Tool activity showed duplicate and empty "gear" cards from partial/re-emitted
  tool-call chunks. ToolStarted now de-dupes by tool_call_id, drops id-less
  noise chunks, and fills the name on a later chunk; a tool result with no prior
  card still surfaces as a completed card.
- Tab moved focus off the composer to the scroll region (felt like broken cursor
  logic). Tab is now consumed by the composer (completes a command when the
  palette is open, no-op otherwise).

Adds reducer tests for each case plus a Tab-focus test; 102 TUI tests pass.

* fix(tui): make Esc interrupt an active run (matches the status hint)

The status line advertised "esc interrupt" but Esc was only wired to close the
slash palette, so it did nothing during a run. Esc now: closes the palette when
open, interrupts the active run when streaming, and is a no-op when idle. The
interrupt logic is shared with Ctrl+C via _interrupt_run(). Adds a regression
test.

* fix(tui): stop prior answers duplicating on threads with history

On a thread with history, DeerFlowClient re-emits every prior message on each
new turn (its streamed_ids dedup is per-stream-call), and a re-emitted older
message can arrive after a newer message has already started. The reducer only
matched the *most recent* assistant row by id and otherwise appended, so each
re-emitted older answer was duplicated verbatim at the end of the transcript.

Match an assistant row by id anywhere in the transcript and merge in place.
Tool cards already de-dupe by call id globally, so they were unaffected.

* fix(tui): correct CJK cursor drift in the composer

Confirmed a Textual Input bug (latest 8.2.7): Input._cursor_offset adds an
unconditional +1 at the end of the value, overshooting by one cell after
double-width (CJK) characters. That misplaces the hardware/IME cursor — the
drift seen when typing Chinese in iTerm2 (the on-screen block cursor, drawn
separately in render_line, is fine; English doesn't use an IME so it looks
correct). Reproduced with a bare Input, so it's upstream, not our layout.

Add ComposerInput(Input) overriding _cursor_offset to the true cell position and
use it for the composer. Numeric tests pin the CJK end/mid and ASCII cases.

* feat(tui): render finalized assistant messages as Markdown

The transcript showed raw Markdown (literal **bold**, ## headings, - lists,
links). Finalized assistant messages now render as Rich Markdown — headings,
bold/italic, lists, inline code + code blocks, blockquotes, horizontal rules and
links — with the ● speaker marker aligned to the top of the body.

The actively-streaming message stays plain text so partial Markdown doesn't
reflow/jump, then snaps to its rendered form when the run ends. Transcript
re-renders are coalesced on a ~60ms timer (dirty flag) so per-token Markdown
re-parsing stays smooth on long threads. Tests cover both the rendered and the
streaming-plain paths.

* style(tui): apply ruff format

CI lint runs `ruff format --check` via uvx (latest ruff); apply the formatter so
the lint-backend job passes. No behavior change.

* chore(tui): address code-quality review comments

From github-code-quality[bot] on #3760:
- runtime.py: give the `_ClientLike` Protocol method a docstring body instead of
  a bare `...` (flagged as a no-effect statement), matching the harness
  convention for Protocol stubs (e.g. SafetyTerminationDetector).
- test_tui_cli_main.py: drop the unnecessary `lambda: _FakeSession()` wrappers in
  monkeypatch.setattr; pass `_FakeSession` directly (same behavior).

* fix(tui): keep history Markdown-rendered when a follow-up run starts

Previously the transcript rendered "the last assistant row" as plain text while
streaming. But when a follow-up turn starts, the last assistant row is the
*previous, finalized* answer until the new message begins — and the client
re-emits prior messages early in the turn — so sending a follow-up reverted the
previous answer from rendered Markdown back to raw text.

Track the actively-streaming message id in ViewState instead: it's reset on
RunStarted, set only when an AssistantDelta actually adds new content (history
re-emits are no-ops and don't mark it), and cleared on RunEnded. The renderer
keeps only that one message plain; all history stays Markdown.

* docs(readme): add Terminal Workbench (TUI) section to root README

Mention the new `deerflow` TUI alongside the Embedded Python Client in the root
README.md and README_zh.md (install, launch/headless commands, feature summary,
Web UI visibility), with a ToC entry and a preview screenshot. Links to
backend/docs/TUI.md for the full guide.

* fix(tui): address review feedback (willem-bd)

Ten findings from the TUI code review:

1. /resume was dead-ended — registered + in /help + tested as a builtin, but no
   dispatch branch. Wired it to thread resolution / the switcher.
2. --resume <title> was forwarded raw into the checkpointer (blank thread).
   Added Session.resolve_ref() to resolve id-or-title via list_threads; used by
   --resume and /resume.
3. str(get("id","")) returned "None" for an explicit id:None (truthy), defeating
   the empty-id guard so unrelated null-id tool calls collapsed into one card.
   Coerce via a None-safe helper.
4. Headless --print/--json no longer spin up the persistence loop/engine/pool
   (open_session(persistence=False)).
5. _LoopThread + engine are now closed: Session.close() (dispose engine + stop
   loop) called from a try/finally around app.run().
6. --cli --continue (and piped --cli) now run headless instead of erroring.
7. Cancelled runs no longer persist a truncated title (guard on _cancelled).
8. Palette highlight resets to the top when the filter set changes.
9. Dropped the never-populated tools count from the header.
10. Documented the `not row.error` merge guard.

Adds regression tests for each; 126 TUI tests pass, ruff check + format clean.

chore(deps): sync uv.lock with groundroute extra (#3678)
The deerflow-harness pyproject.toml declares a groundroute optional
extra (added in #3675), but uv.lock provides-extras was left out of
sync. Regenerate the lock so the declared extra is recorded.
